Nerillids are small marine annelids, once placed at the artificial group ‘Archiannelida’, which contained all families of the exclusively interstitial polychaetes. Nerillidae is the most species rich family among them, with 71 species grouped into 15 genera, and represents an important component of the interstitial fauna, occupying a wide bathymetric range. Despite its problematic placement among the ‘Archiannelida’ families, the group per se is considered monophyletic. Currently, only two species of Paranerilla are valid, both being reported from the northern hemisphere. It is presented herein as the first description of a species of Paranerilla from tropical waters, named as Paranerilla schiavettii sp. nov., which is also considered as a unique record by the presence of a modified acicular spine in noto- and neuropodia from chaetiger 3–7, not mentioned in its congeners descriptions. Hence, we also propose an emendation on the genus diagnosis to embrace the presence of acicular spines within Paranerilla. So, the presented information complements the current knowledge about the group’s taxonomy and expands its distribution to South Atlantic waters.
In the present study, a revision of the phylogeny and taxonomy of the family Dorididae is carried out focusing on the genus Doris Linnaeus, 1758. The type species D. verrucosa Linnaeus, 1758 and a blueish and yellow morphotype of D. ocelligera collected in different localities in the Mediterranean Sea and the North-East Atlantic were sequenced, as well as D. bertheloti and the elusive D. marmorata for the first time. The genetic markers include the cytochrome c oxidase subunit I, 16S rRNA, and histone 3. The phylogenetic results suggest that the genus Doris is paraphyletic, and D. ocelligera morphotypes separate into two species, as confirmed with species delimitation tests. To complement the phylogenetic evidence with morphoanatomical data, the dissection of two specimens of each morphotype is conducted. Significant differences in morphological traits such as body shape, colouration patterns, and mantle tubercles come to light, together with anatomical differences in the relative shape and size of the radular teeth and reproductive structures. Considering the modern and old descriptions of D. ocelligera, it is finally concluded that the blueish morphotype belongs to D. ocelligera. In contrast, the yellow morphotype responds to the actual synonym Aldisa berghi (Vayssière, 1901), which is resurrected here as Doris berghi comb. rest. Considering the broad phylogeny of the family, some systematic notes at the genus level are here provided.
New World lampyrid taxonomy faces severe taxonomic impediments. Most species remain known from original taxonomic descriptions only, often insufficient for accurate identification. Therefore, the study of type specimens is critical to ensure proper identification. The Russian entomologist Viktor Ivanovich Motschulsky was one of the most important authors of firefly (Coleoptera: Lampyridae) taxonomy during the XIXth century, and his work is still relevant today. Part of his material, including the type specimens of several species, is deposited at the Zoological Institute of the Russian Academy of Sciences. Unlike their European, Asian, and Oceanian counterparts, the taxonomy of Neotropical fireflies is still in its infancy, partly due to largely outdated literature and difficulties in accessing type specimens. Here, we review the type specimens of 38 firefly species deposited at ZIN, 15 of which are holotypes and 7 are lectotypes. For each specimen, the name-bearing status, condition of preservation, as well as the associated label data are provided. Lectotypes are designated for the following species described by Motschulsky: Bicellonycha lividipennis, Ellychnia californica, Lychnuris klugii, Macrolampis longipennis, Pseudolychnuris suturalis, Telephoroides lineaticollis, Telephoroide occidentalis.
Four new species of the genus Catonidia Uhler, 1896, C. triangula sp. nov., C. saccata sp. nov., C. trilobata sp. nov. and C. uncinata sp. nov. from China (Fujian, Guizhou, Yunnan and Hainan provinces), are described and illustrated, giving the genus 14 species in total. A checklist and key to all known species of Catonidia are provided, as well as a map of their geographic distributions.
Phyllanthus novofriburgensis J.C.R.Mendes, J.M.A.Braga & Fraga sp. nov. and P. pedrosae J.C.R.Mendes, J.M.A.Braga & Fraga sp. nov. are new species of Phyllanthaceae described from the Brazilian Atlantic Forest and Brazilian Cerrado, respectively. Phyllanthus novofriburgensis resembles P. acutifolius Poir. ex Spreng., P. hypoleucus Müll.Arg. and P. lilliputianus J.C.R.Mendes, J.M.A.Braga & Fraga, sharing ovate, elliptical, and lanceolate leaf blades. However, it can be distinguished by its pendulous habit, often with sinuous branches and lanceolate leaf blades with characteristically revolute margins. Phyllanthus pedrosae exhibits morphological similarities with P. claussenii Müll.Arg. due to its subshrubby and prostrate habit. It is distinghuished by the unisexual inflorescence with cymules composed of one or two staminate flowers proximally positioned in the axil of the branches and solitary pistillate flowers distally situated, and the 5-merous calyx in the staminate and pistillate flowers. Both new species are classified in Phyllanthus subgen. Phyllanthus sect. Phyllanthus subsect. Clausseniani G.L.Webster, primarily due to the deeply emarginate anthers. Notes on their geographical distribution and habitat are provided, as well as a key to the species of Phyllanthus from Southeastern Brazil.
Four new species of the genus Catonidia Uhler, 1896, C. triangula sp. nov., C. saccata sp. nov., C. trilobata sp. nov. and C. uncinata sp. nov. from China (Fujian, Guizhou, Yunnan and Hainan provinces), are described and illustrated, giving the genus 14 species in total. A checklist and key to all known species of Catonidia are provided, as well as a map of their geographic distributions.

The subfamily Prosympiestinae (Heteroptera: Aradidae) is revised for New Zealand. Three genera and thirteen species are recognized. Five species are described as new: Neadenocoris centralis Larivière and Larochelle new species, Neadenocoris hoarei Larivière and Larochelle new species, Neadenocoris northlandicus Larivière and Larochelle new species, Neadenocoris pseudovatus Larivière and Larochelle new species, Neadenocoris wellingtonensis Larivière and Larochelle new species. One new synonymy is established: Neadenocoris reflexus Usinger and Matsuda, 1959 becomes a junior synonym of Neadenocoris acutus Usinger and Matsuda, 1959. A revision of all taxa is provided. Descriptions, identification keys, illustrations of male parandria, habitus photos, distributional data and maps are given. Extensive information on biology is included for each species.

The small, eyeless beetles of the genus Anillinus Casey (Coleoptera: Carabidae: Trechinae: Anillini) comprise a diverse, ubiquitous, but poorly known component of insect biodiversity in the southeastern United States. Their limited dispersal capabilities make them ideal subjects for biogeography, but taxonomic problems and undescribed species diversity hamper such studies. In this paper, we redescribe four enigmatic species, Anillinus docwatsoni Sokolov and Carlton, Anillinus elongatus Jeannel, Anillinus pecki Giachino, and Anillinus turneri Jeannel, and consider their relationships. The elongatus species group is revised, with descriptions of four newly discovered species, Anillinus arenicollis Harden and Caterino, new species, Anillinus montrex Harden and Caterino, new species, Anillinus pittsylvanicus Harden and Caterino, new species, and Anillinus uwharrie Harden and Caterino, new species. Two species previously considered part of the elongatus group are determined to not belong here, Anillinus cavicola Sokolov and Anillinus turneri Jeannel. The exact placement of A. turneri remains uncertain, but it shares some character states with the sinuaticollis group. We erect the pecki group for A. docwatsoni and A. pecki, which are likely sister species. We provide a key to the eastern species groups of Anillinus and the species of the elongatus and pecki species groups. Anillinus pecki is broadly distributed in the southern Appalachian Mountains northeast of the French Broad River basin, while A. docwatsoni is apparently endemic to the Hickory Nut Gorge in western North Carolina. Anillinus pecki is reported for the first time from Tennessee and Virginia. All members of the elongatus group have small geographic ranges and are difficult to sample without special techniques, hinting that many more species await discovery in the densely populated Piedmont region of North Carolina, where natural habitats are rapidly being lost. Our sampling was not dense enough to test biogeographic hypotheses, but distributions of the elongatus group species suggest that hydrochory might have played an important role in passive dispersal and reproductive isolation. These taxonomic contributions will facilitate future studies on the genus and serve to highlight the rich insect biodiversity that remains to be discovered in the southeastern United States.

The Chinese members of the genera Leptothorax Mayr, 1855 and Temnothorax Mayr, 1861 are reviewed based on the morphological characters of the worker caste, and 66 species are recognized in China to date. A new synonym is proposed: T. opaciabdomin (Chang & He, 2001) is a junior synonym of T. mongolicus (Pisarski, 1969). Twenty-eight new species of Temnothorax, T. bailu sp. nov., T. chun sp. nov., T. chunfen sp. nov., T. chushu sp. nov., T. dahan sp. nov., T. dashu sp. nov., T. daxue sp. nov., T. dong sp. nov., T. dongzhi sp. nov., T. guyu sp. nov., T. hanlu sp. nov., T. jingzhe sp. nov., T. lichun sp. nov., T. lidong sp. nov., T. liqiu sp. nov., T. lixia sp. nov., T. mangzhong sp. nov., T. qingming sp. nov., T. qiu sp. nov., T. qiufen sp. nov.,T. shuangjiang sp. nov., T. xia sp. nov., T. xiaohan sp. nov., T. xiaoman sp. nov., T. xiaoshu sp. nov., T. xiaoxue sp. nov., T. xiazhi sp. nov., T. yushui sp. nov., are described from China based on worker caste. Three species of Temnothorax, T. desioi (Menozzi, 1939), T. susamyri (Dlussky, 1965) and T. volgensis (Ruzsky, 1905) are recorded in China for the first time. The following eight species are recorded in a province or autonomous region of China for the first time: Leptothorax acervorum (Fabricius, 1793) is a new record in Qinghai, Sichuan and Yunnan; Temnothorax angulohumerus Zhou et al., 2010 is a new record in Guizhou and Tibet; T. argentipes (Wheeler, 1928) is a new record in Sichuan and Yunnan; T. mongolicus (Pisarski, 1969) is a new record in Inner Mongolia; T. reticulatus (Chang & He, 2001) is a new record in Beijing, Gansu, Inner Mongolia, Jilin, Shaanxi and Yunnan; T. spinosior (Forel, 1901) is a new record in Yunnan; T. taivanensis (Wheeler, 1929) is a new record in Guizhou, Sichuan and Yunnan; and T. zhejiangensis Zhou et al., 2010 is a new record in Henan and Guangxi. A key based on the worker caste is provided for the 66 known Chinese species.
As insect decline threatens the fauna of Central Europe, “dark taxa” present an obstacle to understanding biodiversity loss. The superfamily Platygastroidea is a dark taxon, with many superficial descriptions requiring examination of type material to characterize and revise species and genera. The Natural History Museum Vienna (Naturhistorisches Museum Wien) is arguably the most important historical collection of Platygastroidea in Central Europe. Type specimens from 85 species in 21 genera and three families are here catalogued and photographically illustrated, including previously undocumented types described by Förster, Kieffer, Nees von Esenbeck, and Ratzeburg. Lectotypes are designated for Anteris bicolor Kieffer, Anteris simulans Kieffer, Hadronotus laticeps Kieffer, Leptacis foersteri Kieffer, Plastogryon investis Kieffer, Plastogryon sagax Kieffer, Prophanurus mayri Kieffer, and Telenomus laeviceps Förster. Trissolcus schimitsheki (Szelényi) syn. nov. is treated as a junior synonym of Trissolcus scutellaris (Thomson) and Telenomus nomas Förster syn. nov. is treated as a junior synonym of Trissolcus semistriatus (Nees). Baeus maculatus (Förster) comb. nov. is transferred from Telenomus. Historical, taxonomic, and curatorial remarks are included, providing an essential foundation for revisionary work on the Platygastroidea of Central Europe and beyond.
Rove beetles (Staphylinidae) are a diverse insect group, especially in the Neotropical region. At the same time, this fauna remains significantly understudied. During our visits to museum collections, we encountered numerous specimens of undescribed species representing the Neotropical genus Neolindus Scheerpeltz, 1933 which was earlier thought to be rare. To address the knowledge gap in the genus, we studied the museum material that resulted in descriptions of 21 new species. Our work involves the redescription of the genus, descriptions of the new species, and an updated identification key to 39 previously described and new species. The newly described species are Neolindus bicornis Guzman, Tokareva & Żyła sp. nov., N. elegans Guzman, Tokareva & Żyła sp. nov., N. longithorax Guzman, Tokareva & Żyła sp. nov., N. luxipenis Guzman, Tokareva & Żyła sp. nov., N. maya Guzman, Tokareva & Żyła sp. nov., N. minutus Guzman, Tokareva & Żyła sp. nov., N. napo Guzman, Tokareva & Żyła sp. nov., N. niger Guzman, Tokareva & Żyła sp. nov., N. ornatus Guzman, Tokareva & Żyła sp. nov., N. parahermani Guzman, Tokareva & Żyła sp. nov., N. paraplectrus Guzman, Tokareva & Żyła sp. nov., N. parasinuatus Guzman, Tokareva & Żyła sp. nov., N. parautriensis Guzman, Tokareva & Żyła sp. nov., N. pseudosensillaris Guzman, Tokareva & Żyła sp. nov., N. sauron Guzman, Tokareva & Żyła sp. nov., N. sibyllae Guzman, Tokareva & Żyła sp. nov., N. triangularis Guzman, Tokareva & Żyła sp. nov., N. tropicalis Guzman, Tokareva & Żyła sp. nov., N. utriensis Guzman, Tokareva & Żyła sp. nov., N. volkeri Guzman, Tokareva & Żyła sp. nov., and N. yotokae Guzman, Tokareva & Żyła sp. nov. This research emphasises the importance of museum collections in advancing taxonomy and enriching biodiversity knowledge. With these contributions, the known number of species of Neolindus reaches 60, thereby enhancing data on the Neotropical rove beetles diversity. Additionally, we provide several new country records for the genus (Guyana, Mexico, Nicaragua, and Suriname), which widen its distribution, and new occurrence records for the described species of Neolindus, N. agilis Herman, 1991; N. apiculus Herman, 1991; N. basisinuatus Herman, 1991; N. campbelli Herman, 1991; N. cuneatus Herman, 1991; N. hermani Asenjo, 2011; N. irmleri Asenjo, 2011; N. lodhii Herman, 1991; N. procarinatus Herman, 1991; N. punctogularis Herman, 1991; and N. retusus Herman, 1991.
The fossil record of the diverse subfamily Passifloroideae (>750 species and 17 genera) is relatively poor. Despite the distinctiveness of its leaves (glandular and often emarginate), most of the fossils from this group have been described from seeds. Fossil seeds have been recovered from Europe, and North and South America. A lack of information on seed morphology for all the genera and tribes of this subfamily has prevented a tribe-level identification of the fossils and a better understanding of their biogeographic patterns. The Passifloroideae is divided into three tribes: Passifloreae with 10 genera, Paropsieae with six genera and the monotypic Jongkindieae. This study provides new descriptions for 15 species from 5 genera from the mostly Afrotropical tribe Paropsieae based on herbarium material, and introduces an online seed database and a key for 100 species of Passifloroideae compiled from literature and direct observations. Our study shows a low morphological diversity among the seeds of Paropsieae in comparison to a much larger diversity within Passifloreae. Some rare morphologies are only present in Passifloreae and can be used to assign seeds to this tribe. Within the Paropsieae, Androsiphonia has seed that are very distinct from those in the other genera in the tribe and also from the rest of the subfamily. The genus Paropsia exhibits two main morphotypes, while the genera Barteria, Paropsiopsis and Smeathmannia have very similar seeds with a highly conserved morphology. These results suggest that living or fossil Paropsieae cannot be identified confidently based solely on seed characters.
Four new species of the Australian genus of Eurybrachidae (Hemiptera, Fulgoromorpha) Olonia Stål, 1862 are described from northern Queensland: O. albomarginata sp. nov., O. aschei sp. nov., O. jackiei sp. nov. and O. lindae sp. nov. Host plants and natural history data are documented and additional new records provided for O. guillaumei Constant, 2018, O. hochae Constant, 2018, O. picea Kirkaldy, 1906, O. rubicunda (Walker, 1851) and O. soulierae Constant, 2018. Trophobiosis is recorded for the first time in the genus, between a female of O. hochae and ants of the genus Camponotus Mayr, 1861 (Hymenoptera, Formicidae), representing the second record of trophobiosis in Australian Eurybrachidae. The male terminalia of the new species are illustrated and photographs of collection and live specimens, distribution maps, biological data and an identification key are provided. The genus Olonia currently contains sixteen species.
Twenty-one species of Mysidae were sampled by three ANDEEP expeditions to the Southern Ocean with epibenthic sledges dragged over the deep-sea floor in the realm of 58–71° S and 00–65° W, depth 774–5190 m. Previously known ranges are significantly extended southward for four species and to greater depth in the same four species plus two other species. Supplementary descriptions are given for Amblyops tattersalli and Dactylamblyops murrayi, and a first description of a (subadult) male for Thalassomysis tattersalli. The definitions of the genera Amphiakrops gen. nov., Chelamblyops gen. nov., Desmocornea gen. nov. and Schizurakrops gen. nov. are mainly based on the structure of the eyes as well as of the antennal peduncle, chelate second thoracic endopod and telson. These structures are also important for the descriptions of Amblyops arianii sp. nov., A. bipapillatus sp. nov., Amblyopsoides fenestragothica sp. nov., A. lepidophthalma sp. nov., Amphiakrops brandtae gen. et sp. nov., Dactylamblyops benthophilus sp. nov., Desmocornea subchelata gen. et sp. nov., Paramblyops petrescui sp. nov., Schizurakrops meesi gen. et sp. nov., Scolamblyops muehlenhardtae sp. nov., Stellamblyops doryphorus sp. nov. and Mysidella antarctica sp. nov. Six previously described taxa are recombined as Amblyopsoides laticauda comb. nov., Amphiakrops bidigitatus comb. nov., A. japonicus comb. nov., Chelamblyops globorostris comb. nov., Meierythrops tattersalli comb. nov. and M. triangulatus comb. nov. One species is revised back to the initial combination as Dactylamblyops japonicus. All except one (Mysidella antarctica sp. nov.) newly described (12), newly recombined (6) or back-combined (1) species belong to the Erythropinae. Keys to the resulting 61 genera and 263 species of Erythropinae and 18 species of Mysidellinae are given at the world-wide scale. Ocular papillae with a terminal pore (sensory pore organ) are recorded in nine ANDEEP species. The organ of Bellonci is identified on the reduced eyes in 16 species, among which D. subchelata gen. et sp. nov. has many ommatidia arranged in a self-contained ribbon which shows a banded rhabdom only in non-adults. Reduction of visual elements together with shrinking of ocular papillae during ontogenetic development suggest that non-adults of D. subchelata and T. tattersalli stay in the photic zone for feeding and growth and then descend only once during their lifetime to the abyss for reproduction.
Until now, the genus Porcelliniodes Miers, 1877 is represented in the Ibero-Balearic region by seven species. The study of 721 specimens from Portugal and Spain has led to the identification of 11 species, including poorly known species, and the description of a new species, Porcellionides ibericus sp. nov. This new species is characterized by the absence of transverse ridges on the pereonites, medium-sized lateral lobes on the cephalon, the pleon slightly retracted in relation to the pereon, pereopods without sexual differentiation, and a truncated posterior inner tip in the male pleopod I. We consider P. glaber (Koch, 1856), P. hispanus (Vandel, 1953), P. lucasioides (Vandel, 1953), P. lusitanus (Vandel, 1946), and P. molleri (Verhoeff, 1901) as valid species, while P. buddelundi (Verhoeff, 1901) and P. rufocinctus (Dollfus, 1892) are considered species inquirendae. Five species are recorded for the first time in some Portuguese districts and seven in some Spanish provinces.
Research on the Heteroptera fauna of Turkey has not been extensive enough to illustrate its true diversity. Although several factors contribute to this, the lack of an up-to-date and comprehensive review is a basic factor. To address this issue, we compiled a list of all the Heteroptera species recorded from Turkey in the literature and iNaturalist. In addition, we re-examined several specimens preserved in the Lodos Entomological Museum, İzmir, Turkey (LEMT). Consequently, we excluded 24 species from the checklist of Heteroptera fauna of Turkey, and proposed a new synonymy: Psallus (Psallus) pardalis Seidenstücker, 1966 = Psallus (Psallus) oenderi Wagner, 1976 syn. nov. Furthermore, we recorded following six species from Turkey for the first time: Blissus hirtulus Burmeister, 1835 (Blissidae), Loricula (Loricula) pselaphiformis Curtis, 1833 (Microphysidae), Globiceps (Globiceps) coryli V.G. Putshkov, 1970, Heterocordylus (Heterocordylus) cytisi Josifov, 1958, Mesopsallus fagi (Drapolyuk, 1990) and Psallus (Psallus) helenae Josifov, 1969 (Miridae); and described following six species as new for science: Orthonotus efei Çerçi & Koçak sp. nov., Orthotylus (Parapachylops) oenderi Çerçi, Tezcan & Koçak sp. nov., Orthotylus (Pinocapsus) girayi Çerçi & Tezcan sp. nov., Psallus (Psallus) eceae Çerçi & Koçak sp. nov., Psallus (Psallus) pehlivani Çerçi & Tezcan sp. nov. and Ribautocapsus tezcani Çerçi sp. nov. Altogether, 1668 species of Heteroptera have been recorded from Turkey (664 species in the European part and 1633 species in the Anatolian part) until now, out of them, the presence of 37 species needs confirmation. We determined the chorotypical composition of species as follows: Mediterranean (399 spp., 23.9%), European (380 spp., 22.8%), Local (280 spp., 16.8%), Widespread (182 spp., 10.9%), Endemic (128 spp., 7.7%), Turanian (127 spp., 7.5%), Turano-Mediterranean (89 spp., 5.3%), Europeo-Mediterranean (68 spp., 4.1%) and Alien (12 spp., 0.7%). We showed that provinces in the Eastern Anatolian, Southeastern Anatolian, and Black Sea regions had lower numbers of species recorded, compared to the provinces in the remaining regions. Finally, we underlined that 109 species, absent from Turkey, were recorded from three or more neighboring countries of Turkey. In summary, our findings emphasize that despite the abundant research devoted over the last 150 years to the Heteroptera fauna of Turkey, our understanding of it remains incomplete in the majority, if not in all, of the regions. Our findings strongly encourage further research, particularly in regions with small numbers of recorded species. This endeavor will undoubtedly lead to numerous novel discoveries and provide a better understanding of the true Heteroptera diversity in Turkey.
Two new species of Perinereis with single bar-shaped paragnaths on area VI (Group 1) from the rocky shores of Mumbai, Maharashtra, India, are described with barely (Subgroup 1A) or largely (Subgroup 1B) expanded proximal region of dorsal ligule in posterior parapodia. Perinereis malabarensis sp. nov. can be distinguished from the morphologically similar 1B species P. euiini Park & Kim, 2017 by the paragnath count in area I, the laterally isolated paragnaths in area III, and the length of the dorsal cirrus and dorsal ligule. Additionally, P. misrai sp. nov. is more similar to 1A species P. falsovariegata Monro, 1933 and P. villalobosi Rioja, 1947, but differs by the paragnath count in areas III–V and VII–VIII, the isolated paragnaths in area III, and the number of rows in the anterior band of areas VII–VIII. The morphological characters of the current 44 species within Perinereis G1 are compared, and an identification key to the species belonging to this group is also provided.
The taxonomic status of recently described Isophya taxa from Serbia (Tettigoniidae, Phaneropterinae)
(2024)
During recent decades, increasing research of the taxonomy of the genus Isophya resulted in taxonomic descriptions of several new species. The delimitation of these species is mainly based on oscillographic song analysis of the male song in combination with morphological characters, such as the shape of male cerci, tegmina and ovipositor. In the present paper, we used an integrative taxonomic approach in order to resolve the status of four recently described Isophya taxa from Serbia. Based on our molecular and bioacoustic analyses, all analyzed taxa belong to a single species: Isophya modestior. The majority of the morphological characters used to differentiate the taxa showed strong intra- and interpopulational variability, proving that describing new species within the genus Isophya should not rely on morphological characters alone, but needs to consider bioacoustic analyses as the main tool and a larger series of specimens.
A collection of 1149 otoliths of the Ypresian and Ypresian–Lutetian transition (early Eocene) from 18 sites across five states in the eastern and southern regions of the USA was analyzed. In total, 33 otolith-based taxa are documented, of which 27 are identified at the species level. Nine of these are introduced as new species: “Conger” biaculeatus sp. nov., Bauzaia gibbosa sp. nov., Ampheristus brevicaudatus sp. nov., Symmetrosulcus virginicus sp. nov., Neobythites longesulcatus sp. nov., “Neobythites” pamunkeyensis sp. nov., “Neobythites” stringeri sp. nov., Waitakia dorsogibbosa sp. nov., and “Haemulon” ypresiensis sp. nov. The assemblages are distinct when compared to their younger Eocene counterparts in America. This distinction is primarily characterized by the high proportion of the newly introduced species or exclusive Ypresian species. Additionally, we highlight the presence of 10 amphi-Atlantic species originally described in European deposits. Significantly, the composition of the otolith collection supports the interpretation of a shallow-water environment for the sampled sites during the Ypresian. This ecological setting appears to persist into the subsequent middle and late Eocene within the same geographic region.
The genus Legua Walker, 1870 comprises only two known species from Central America and Brazil, with a notable scarcity of collected specimens. Herein, we provide a new contribution to our knowledge of the distribution of Legua rosea Amédégnato and Poulain, 1986 (Romaleinae: Leguini), that has a restricted distribution in Brazil, based on entomological collection data and social media information. Our records emphasize the importance of natural history collections and new tools for biodiversity studies.

A new species of Paranthrene Hübner (Lepidoptera: Sesiidae) from the northern midwest United States
(2024)
A clearwing moth species, Paranthrene sogaardi Taft and Smith, 2024, new species, is described from Michigan and Minnesota. The recognition of this new species is based on a phylogeny estimated from mitochondrial cytochrome oxidase I and wingless DNA sequences of 25 specimens representing all Paranthrene Hübner species including individuals from various locations. Paranthrene sogaardi new species was monophyletic and differed from Paranthrene tabaniformis Rottenburg, 1775 by a mean of 7.6% COI pairwise “p” distance, coloration, and genitalic morphology.

Hurd (1952) separated Pepsis cerberus Lucas from P. elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini) based on external morphology and biogeography. Vardy (2005) synonymized the familiar and historically well-documented P. cerberus and P. elegans, combining these Nearctic taxa with several Neotropical variants in an extremely broad definition of P. menechma Lepeletier. In doing so, Vardy (2005) breached the principle of nomenclatural stability. He ignored the prevailing usage and clearly violated articles 23.2, 23.3 and 23.9.1.2 of the ICZN (1999). Morphological differences, ecological divergence, and narrow sympatric geographic distribution of P. cerberus and P. elegans contradict Vardy (2005) and justify full species status (Kurczewski 2023a). Furthermore, we propose the removal of the two species from the P. menechma list of synonyms and recommend full species reinstatement as Pepsis cerberus, restored status and Pepsis elegans, restored status. Pepsis menechma becomes a senior synonym of P. elegans. Morphometric re-examination and statistical analysis of P. cerberus and P. elegans structural features strongly support their reinstatement. Quantitative measurement of 10 parasitoid-related morphological characteristics of the females revealed the two species differ significantly in frons width/head width, head length/head width, vertex length/head width, vertex length/head length, flagellomere 1 length/flagellomere 1 width, forewing length/mesosoma width, and hind tibial inner spur length/hind basitarsus length. Pepsis cerberus and P. elegans females are structurally and statistically similar in gena-postgena corner radius, fore femur width/mesosoma width, and number of hind tibial serrations.

The geographic distributions of three large wasps, Sphecius speciosus (Drury), Stictia carolina Fabricius and Stizus brevipennis Walsh (Hymenoptera: Crabronidae), occurring in Arkansas are defined using museum specimens and three internet-based data platforms. The internet-based data platforms generally provided more county location records than museum records. Using data from internet sources for easily identified species can better serve to illustrate the known distributions for some species thus making for a powerful tool elucidating distributional patterns and conservation planning.

The exclusively New World velvet ant genus Timulla Ashmead, 1899 (Hymenoptera: Mutillidae: Mutillinae: Trogaspidiini) contains 180 species and ten subspecies. Most of these species are known from a single sex, and the validity of the subspecies has not been evaluated since their original description in 1937 and 1938. The Timulla fauna of the United States of America includes thirty species and eight subspecies, and the fauna of Canada includes three species. The faunas of these two countries were critically studied with the following results. Out of the eight total subspecies, seven were found to be structurally identical to and sympatric with the nominate subspecies. The subspecific differences were limited to cuticle and/or setal coloration in males and intergrades between them were found in several cases. With the senior synonym listed first, seven subspecies-level synonymies are proposed, which include: Timulla barbigera (Bradley, 1916) = T. barbigera rohweri Mickel, 1937, new synonym; T. dubitata (Smith, 1855) = T. dubitata fugitiva Mickel, 1937, new synonym; T. hollensis (Melander, 1903) = T. hollensis melanderi Mickel, 1937, new synonym; T. ocellaria Mickel, 1937 = T. ocellaria rufidorsa Mickel, 1937, new synonym; T. suspensa (Gerstaecker, 1874) = T. suspensa jonesi Mickel, 1937, new synonym, = T. suspensa sonora Mickel, 1937, new synonym; T. vagans (Fabricius, 1798) = T. vagans rufinota Mickel, 1937, new synonym. The final remaining subspecies, Timulla navasota coahuila Krombein, 1951, is raised to a full species, Timulla coahuila Krombein, 1951, new status, based on its unique female morphology. Also, four new sex associations are proposed, which include: Timulla barbata (Fox, 1899) = T. wileyae Mickel, 1937, new synonym; T. euterpe (Blake, 1879) = T. compressicornis Mickel, 1937, new synonym; T. neobule Mickel, 1937 = T. nicholi Mickel, 1937, new synonym; T. subhyalina Mickel, 1937 = T. dubitatiformis Mickel, 1937, new synonym. The former species, T. dubitatiformis, which was previously known only from females, is here recognized as being a morphologically-conservative complex of species; its synonymy with T. subhyalina effectively associates the remaining male-based members of the Timulla ocellaria species-group with it as well, which includes Timulla hollensis (Melander, 1903), T. kansana Mickel, 1937, T. ocellaria Mickel, 1937, T. rufosignata (Bradley, 1916), T. sayi (Blake, 1871), T. subhyalina Mickel, 1937, and T. tolerata Mickel, 1937. Further, two species-level synonymies are proposed, which include: Timulla dubitata (Smith, 1855) = T. murcia Mickel, 1938, new synonym; T. vagans (Fabricius, 1798) = T. huntleyensis Mickel, 1937, new synonym. Finally, Timulla cyllene (Cameron, 1894) is newly recorded in the United States of America from the state of Arizona.

The nine genera of Malagasy spittlebug are revised, with the addition of new characters, facilitating the identification of the species. Nesaulax Jacobi, 1917, is synonymized with Amberana Distant, 1908, leading to a new combination for Amberana vittipennis (Bergroth, 1894). A new endemic genus Soulierana Bucher & Bouteille gen. nov. is proposed for two species originally placed in Literna Stål, 1866, based on morphological characters of the head, tegmina and male genitalia. Also, three new species are described in this genus: Soulierana bigidea Bucher gen. et sp. nov., Soulierana claudinae Bouteille gen. et sp. nov. and Soulierana kelymena Le Cesne gen. et sp. nov. Pictures of species and drawings of the male genitalia for all genera, with the exception of Rhinaulax Amyot & Serville, 1843, Alluaudensia Lallemand, 1920 and Literna, are included. An identification key is available in both a dichotomous format and an interactive format (Xper3).
Systematics of the Sierra Nevada endemic earwig: Eulithinus analis (Forficulidae, Dermaptera)
(2024)
Since the description of Eulithinus analis (Rambur, 1838) the taxonomic position of this Sierra Nevada endemic earwig has been controversial. It has been subdivided in different taxa, assigned to various genera or transferred to different subfamilies. With the aim of clarifying its systematics, we performed a mitochondrial phylogeographic analysis using specimens from different localities of Sierra Nevada representing the diverse phenotypes treated as differentiated taxa until now, and a phylogenetic analysis including representatives of apparently distant, but morphologically close, relatives. The phylogenetic and phylogeographic results obtained using mitochondrial (cytb, cox1) and nuclear (ITS2) markers and the study of morphological characters, indicate that the Sierra Nevada Mountain Range harbors a single species of the genus Eulithinus. Based on these molecular data, the morphological characters used to date in the internal taxonomy of this group of earwigs, especially size and shape of the cerci, lack diagnostic validity and show a large inter- and intra-populational variability. These results imply the synonymy of Eulithinus montanus (Steinmann, 1981) with Eulithinus analis (Rambur, 1838) syn. nov. and the reconsideration of Eulithinus analis outside the subfamily Allodahliinae. We established the synonymy between Eulithinus analis (Rambur, 1838) and Forficula brevis Rambur, 1838 syn. nov., a name that must be removed from the synonymy of Forficula decipiens Gené, 1832.
Two new species of Fomitopsidaceae, Pseudofomitopsis fusca R.Saha, A.K.Dutta & K.Acharya sp. nov. and Fomitopsis benghalensis R.Saha, A.K.Dutta & K.Acharya sp. nov., are described from West Bengal, India, based on morphological and molecular phylogenetic analyses (nuclear ITS sequence). Pseudofomitopsis fusca sp. nov. possesses perennial, triquetrous to ungulate, sessile basidiocarps with a shiny, glabrous, azonate, dark brown upper surface, a yellowish grey pore surface with angular pores (3–5 per mm), a dimitic type of hyphal system with clamped generative hyphae, fusoid cystidioles; ellipsoid, cotton blue positive, and basidiospores 3–5 × 1.5–3.5 µm. Fomitopsis benghalensis sp. nov. is characterized by its annual, resupinate basidiocarp with pilose, bluish white to orange-grey, warty, woody upper surface, bluish-white pore surface, circular to angular pores (5–7 per mm), a trimitic type of hyphal system with clamped generative hyphae, fusoid cystidioles, and cylindrical to elongate basidiospores (5.5–8 × 2.5–3.5 µm). The new taxa are compared to closely related taxa. Photomicrographs of the basidiocarps, along with detailed morphological descriptions and a molecular sequence-based phylogenetic tree, are provided.
We review the diagnosis of the genus Eugenys Quate, 1996 (Diptera: Psychodidae) which occurs in the Neotropical Region. Initially known from Costa Rica, Nicaragua, and Panama, we describe one additional species from Costa Rica, Eugenys singularis sp. nov., and two species from Ecuador, namely, Eugenys micra sp. nov. and E. upsilon sp. nov., bringing the total known species to six. This study provides detailed descriptions of the new species based on male and female specimens, along with the first DNA barcodes for the genus and some of the newly described species. We also provide an identification key for identifying male specimens of the genus worldwide. Finally, we discuss the morphological characteristics of Eugenys and compare the genus with other taxa, tentatively suggesting a placement within the tribe Pericomaini.
Two species new to science Willowsia sikkimensis sp. nov. and W. arunachalensis sp. nov., and one new record of the genus Willowsia Shoebotham, 1917 are described and illustrated here. The new species are mainly distinguished from the others on the basis of pigment pattern, scale type and chaetotaxy. The species were collected from the states of Arunachal Pradesh and Sikkim (India). Willowsia shiae Pan, Zhang & Chen, 2006 is recorded for the first time from India (Arunachal Pradesh) and redescribed with detailed chaetotaxic nomenclature. A key to the Indian species of Willowsia and a comparison table of related species are also provided.
A new genus and species of Parabathynellidae (Crustacea: Bathynellacea), Megabathynella totemensis Camacho & Abrams gen. et sp. nov., is described from the Northern Territory, Australia. This species is the first to be described from an Australian cave. It is a new giant species (4 to 6 mm). The new species displays several unique morphological character states within Parabathynellidae and is the only known species with: more than 12 articles on antennules, with a short, curved barbed seta on each article from the fifth; eight setae on the last article of antennae; more than three setae on the mandibular palp; up to 17 articles on the exopod of the thoracopods, without ctenidia but with a strong spine on each article at the base of the external seta; strong row of pair of spines on latero-external side of second article of endopod in all thoracopods; the male thoracopod VIII is different from all those known; more than 50 spines on the sympod of the uropod and more than 35 spines on the furcal rami. Specimens of the new species are morphologically different from all known species, but more closely resemble some giant species of the genera Kampucheabathynella (Asia), and Billibathynella and Brevisomabathynella (Australia).
Five new species of the genus Phlugiolopsis Zeuner, 1940 (Tettigoniidae: Meconematinae) from China
(2024)
This paper reports five new species of Phlugiolopsis Zeuner, 1940 from Sichuan, Yunnan and Guangxi in China, i.e., Phlugiolopsis luojishanensis sp. nov., Phlugiolopsis lata sp. nov., Phlugiolopsis rongshuiensis sp. nov., Phlugiolopsis acuta sp. nov. and Phlugiolopsis daweishanensis sp. nov. We present a redescription of the male of Phlugiolopsis punctata Wang, Li & Liu, 2012, describe the female of Phlugiolopsis punctata Wang, Li & Liu, 2012 and the male of Phlugiolopsis pentagonis Bian, Shi & Chang, 2013 for the first time. In addition, images illustrating the morphology of these species and seven previously described species are provided. The distribution map of the genus Phlugiolopsis from China is also provided.
Field work in the Kibira National Park (Burundi), located in the Kivu-Ruwenzori system of the Afromontane Region, revealed the existence of a new species clearly belonging to the Argocoffeopsis-Calycosiphonia clade (Coffeeae, Rubiaceae). The species shows striking heterophylly: the plagiotropous branches have several nodes bearing reduced or even scaly leaves. For the rest, it shares characters with Calycosiphonia and Kupeantha. Therefore, a morphological comparison with the clade is done, as well as molecular phylogenetic analyses. The morphology of the novelty is closer to Kupeantha than to Calycosiphonia, inter alia because the anthers have no transverse septa, in contrast to the multilocellate anthers of Calycosiphonia. However, the molecular data advocate for a position in Calycosiphonia – a result weakening the morphological distinction between Calycosiphonia and Kupeantha. The former genus is no longer restricted to species with transverse septa in the anthers and with placental outgrowths around the seed. The new species is formally described as Calycosiphonia albertina Ntore & Robbr. sp. nov. Nomenclaturally, this placement is also the most conservative option. A taxonomic treatment, illustrations, a geographical distribution map, and a preliminary conservation assessment are provided. The previous inclusion of Calycosiphonia pentamera in Kupeantha based on morphology is here corroborated by molecular analyses.
In this second part of the study, using a ‘clean’ dataset without very low precision landmarks and outliers, I describe how to compare mandibular size and shape using Procrustes methods in adult North American marmots. After demonstrating that sex differences are negligible, females and males are pooled together with specimens of unknown sex and species are compared using a battery of tests, that estimate both statistical significance and effect size. The importance of allometric variation and its potential effect on shape differences is also explored. Finally, to provide potential clues on founder effects, I compare the magnitude of variance in mandibular size and shape between the Vancouver Island marmot (VAN) and the hoary marmot, its sister species on the mainland. In almost all main analyses, I explore the sensitivity of results to heterogeneous sample size and small samples using subsamples and randomized selection experiments. For both size and shape, I find a degree of overlap among species variation but, with very few exceptions, mean interspecific differences are well supported in all analyses. Shape, in particular, is an accurate predictor of taxonomic affiliation. Allometry in adults, however, explains a modest amount of within-species shape change. Yet, there is a degree of divergence in allometric trajectories that seems consistent with subgeneric separation. VAN is the most distinctive species for mandibular shape and mandibular morphology suggests a long history of reduced variation in this insular population. Geometric morphometrics (GMM) is a powerful tool to aid taxonomic research. Regardless of the effectiveness of this family of methods and the apparent robustness of results obtained with GMM, however, large samples and careful measurements remain essential for accuracy. Even with excellent data, morphometrics is important, but its findings must be corroborated with an integrative approach that combines multiple lines of evidence to taxonomic assessment. The analytical protocol I suggest is described in detail, with a summary checklist, in the Appendix, not to miss important steps. All the analyses can be replicated using the entire dataset, which is freely available online. Beginners may follow all the steps, whereas more experienced researchers can focus on one specific aspect and read only the relevant chapter. There are limitations, but the protocol is flexible and easy to improve or implement using a programming language such as R.
Taxonomy lays the foundations for the study of biodiversity and its conservation. Procrustean geometric morphometrics (GMM) is a most common technique for the taxonomic assessment of phenotypic population differences. To measure biological variation and detect evolutionarily significant units, GMM is often used on its own, although it is much more powerful with an integrative approach, in combination with molecular, ecological and behavioural data, as well as with meristic morphological traits. GMM is particularly effective in taxonomic research, when applied to 2D images, which are fast and low cost to obtain. Yet, taxonomists who may want to explore the usefulness of GMM are rarely experts in multivariate statistical analyses of size and shape differences. In these twin papers, I aim to provide a detailed step-by-step guideline to taxonomic analysis employing Procrustean GMM in user-friendly software (with tips for R users). In the first part (A) of the study, I will focus on preliminary analyses (mainly, measurement error, outliers and statistical power), which are fundamental for accuracy, but often neglected. I will also use this first paper, and its appendix (Appendix A), to informally introduce, and discuss, general topics in GMM and statistics, that are relevant to taxonomic applications. In the second part (B) of the work, I will move on to the main taxonomic analyses. Thus, I will show how to compare size and shape among groups, but I will also explore allometry and briefly examine differences in variance, as a potential clue to population bottlenecks in peripheral isolates. A large sample of North American marmot mandibles provides the example data (available online, for readers to replicate the study and practice with analyses). However, as this sample is larger than in previous studies and mostly unpublished, it also offers a chance to further explore the patterns of interspecific morphological variation in a group, that has been prominent in mammalian sociobiology, and whose evolutionary divergence is complex and only partially understood.
Belostomatidae Leach, 1815 (Insecta: Hemiptera: Heteroptera: Nepomorpha) of northeastern Brazil
(2024)
Belostomatidae Leach, 1815 (Insecta: Hemiptera: Heteroptera: Nepomorpha), also known as giant water bugs, is a family with 11 genera and about 160 described species, most of which are recorded from the Neotropical region. Knowledge about these bugs in northeastern Brazil is relatively poor, with 16 previously recorded species. Here, we present new records for five additional species based on material from the states of Ceará, Maranhão, and Piauí deposited in the Coleção Zoológica do Maranhão, Caxias, Brazil. This increases to 21 the number of species recorded from the region. In addition, we provide photographs, distribution maps, and a key to the fauna of Belostomatidae from northeastern Brazil.
Taxonomic analysis of the genital plates and associated structures in Ophiuroidea (Echinodermata)
(2024)
Recently, new insights have been gained from the ophiuroid skeleton that were instrumental in the inference of a new phylogeny. The so far least studied ossicles are the adradial and abradial genital plates and the radial shields, which articulate with each other and support the genital slit and disc. In addition, the inner sides of the oral shields and madreporites have never been examined in detail. The present study utilized SEM, micro-CT and digital photography to document and examine these structures in 57 species from 28 of the currently accepted 34 families of Ophiuroidea. Early ontogeny and fossils were also considered. Previously, mainly the articular structures had been analysed, but the overall shape of the genital plates was here found to hold important phylogenetic signals. A long-neglected ossicle was re-discovered and studied in detail for the first time, here named the oral genital plate. It was recognized in all Ophintegrida, but was found to be absent in all Euryophiurida. The oral genital plate articulates with the oral shield and supports the proximal part of the genital slit wall. Abradial and oral genital plates were found to be absent in species that lack genital slits, but the adradial genital plate was always present. Numerous new morphological characters with potential phylogenetic signals were identified, described and figured in detail. A pre-existing character matrix was extended and revised with these new data, as well as with recently revised data on oral papillae, and a Bayesian phylogenetic analysis was performed. This phylogeny largely agrees with the current molecular hypothesis, but some branches were not supported.
Two new species, Habrocestum sahyadri sp. nov., and Irura shendurney sp. nov. are described from the Shendurney Wildlife Sanctuary, Kerala. The unknown female of Habrocestum kerala Asima, Caleb, Babu #38; Prasad, 2022 is described and three other species: Gelotia lanka Wijesinghe, 1991, Phintella accentifera (Simon, 1901) and Vailimia jharbari Basumatary, Caleb #38; Das, 2020 are recorded from the locality. Detailed descriptions, diagnosis and illustrations of the species are provided.
Diospyros L. is a large genus of flowering plants predominantly distributed in the tropics. It comprises over 700 species globally and around 300 are believed to occur in South-East Asia. Many species are economically important and exploited for the production of ebony wood and persimmons, yet taxonomic information on the genus is incomplete and inconsistent due to its morphological and nomenclatural complexity. Revisions of Diospyros in continental and insular South-East Asia were conducted independently by different authors, occasionally with different names used for the same species, or different species being given the same name in different countries. During our ongoing study of the genus Diospyros in Indochina (Cambodia, Laos, Thailand and Vietnam), we identified several such instances. Here, we clarify the most commonly misidentified species, including 1) D. apiculata Hiern, D. strigosa Hemsl. and D. tamiriensis Lecomte; 2) D. bejaudii Lecomte and D. retrofracta Bakh.; 3) D. dictyoneura Hiern and D. hasseltii Zoll.; 4) D. borneensis Hiern and D. fecunda H.R.Fletcher. Lectotypifications are also made for D. brachiata King & Gamble var. lanceolata H.R.Fletcher, D. fecunda, D. similis Craib and D. strigosa.
An update on the diversity and distribution of Caponiidae from Peru is presented. New distributional records for Caponina cajabamba Platnick, 1994 are given and the male is described for the first time. Additionally, three new species of the genus Nyetnops Platnick & Lise, 2007 are described: Nyetnops alexanderi Villarreal & Martínez sp. nov. (♂♀), Nyetnops madre Villarreal & Martínez sp. nov. (♂♀) and Nyetnops josei Villarreal & Martínez sp. nov. (♂). The taxonomic key proposed by Sánchez-Ruiz et al. (2020) for Nyetnops is updated to include all the described species as well as the new ones proposed herein. Maps showing the distribution of the records of Caponiidae species in Peru, mainly focused on the genus Nyetnops is included.
The chenopodium aphid, Hayhurstia atriplicis (Linnaeus, 1761) (Hemiptera: Aphididae), is reported for the first time in Colombia. The aphid was found on the aerial parts of the quinoa plant, Chenopodium quinoa Willd. (Amaranthaceae), especially on the leaves, in five municipalities in the department of Cauca, Colombia. Brief information on its natural enemies, distribution and biology is provided. This is the only aphid in Colombia known to cause malformations on the leaves of quinoa plants. In South America, this aphid has been found previously only in Ecuador, where it was reported for the first time in 2023 based on specimens collected from 2019 to 2021. However, we report that H. atriplicis was likely introduced to Ecuador in the 2000s or earlier, based on a collection dated 2006 found in the United States National Museum of Natural History.

Three species of false click beetles (Coleoptera: Eucnemidae) are added to the Nearctic fauna. One new species, Isorhipis bicolor, is described from a small series collected in Florida, U.S.A. Eighteen specimens collected from Georgia were identified as Dyscharachthis amplicollis (Fleutiaux), new U.S.A. records for a species previously taken from Japan and Southeast Asia. Examination of a series of eucnemids collected by Kyle Schnepp in Florida allowed me to revisit the Deltometopus fauna in eastern North America. Antennal structures present in a series of male specimens in the loan and past examined specimens are definitive enough to resurrect Deltometopus ereptus Bonvouloir, status restored, from synonymy with Deltometopus amoenicornis (Say). Species identification keys are provided for Deltometopus Bonvouloir and Isorhipis Boisduval and Lacordaire in the Nearctic region. Diagnostic differences are briefly noted for each of the three newly added species found in the United States. Images of three species and the related D. amoenicornis are provided.

The review of the taxonomic status of Herpetoreas xenura species complex, based on morphological and molecular data, revealed a new species from Myanmar, which we describe as Herpetoreas davidi sp. nov. from the Rakhine Yoma Elephant Wildlife Sanctuary in Rakhine State. It is suggested to be a sister species to Herpetoreas pealii and Herpetoreas xenura sensu stricto, and can be separated from the latter species by a combination of morphological and scalation characters, and by its pattern. Another population from the Htamanthi Wildlife Sanctuary, Sagaing Region, was previously confused with H. xenura. However, as a closer examination of its morphology, shows it to be closer to Hebius khasiensis, we herein tentatively refer to this population as Hebius khasiensis, pending further molecular data confirming its taxonomic status. Consequently, we propose to temporarily remove Herpetoreas xenura from the fauna of Myanmar. Further studies, especially in the northwestern region of Myanmar, such as near border with India in Chin Hills and Naga Hills, are required. An updated key for the species of Herpetoreas is also provided.
The cosmopolitan pipunculid genus Dasydorylas Skevington, 2001 includes just a few species from the Neotropical Region and is completely unknown to Colombia. Three new species of Dasydorylas are described from protected areas and conflict territories of limited access in Colombia, namely Dasydorylas colombiensis sp. nov. (type locality: Santuario de Fauna y Flora Iguaque, Boyacá), D. gibber sp. nov. (type locality: Santuario de Fauna y Flora Iguaque, Boyacá), and D. santainesensis sp. nov. (type locality: Páramo de Santa Inés, Belmira, Antioquia). Diagnoses, illustrations and distributional data of the new species are presented. Dasydorylas nigellus (Rafael, 1991) is recorded for the first time from Colombia and its amended diagnosis is provided. An identification key to males of all Neotropical species is presented. With this paper, the number of Neotropical species of Dasydorylas is increased from six to nine.
Zebragryllus Desutter-Grandcolas & Cadena-Castañeda, 2014 is a Neotropical genus of field crickets that inhabits the leaf litter of the Amazon rainforest. The genus has six species and is characterized by the distinct ‘zebra’ pattern displayed by some of them. The species are recorded in French Guiana, Peru, and Colombia. Here, we describe two new species of the genus from the Brazilian Amazon rainforest, the first record of the genus for Brazil. We expand the records of Z. guianensis Desutter-Grandcolas, 2014 and Z. nouragui Desutter-Grandcolas, 2014 to Brazil. We also describe but do not name two females corresponding to two new species, provide an up-to-date key for species of Zebragryllus, and discuss the potential distribution for the genus.
